Yes. With cooler temperatures and kids returning to schools, more coughing being heard in supermarkets and public areas. I'll get the COVID-19 and flu shots in a couple weeks. Have not even had a head cold during the 7 years of retirement so far. I strongly dislike being sick. But a couple times did have a runny nose I thought was going to become a head cold but disappeared the next morning like allergies.
Something I've posted elsewhere a decade ago from a no longer online reference with how I keep healthy following that:
...Several studies demonstrate the incidence of the common cold to be highest in preschool and elementary school-aged children. An average of 3-8 colds per year is observed in this age group, with an even higher incidence in children who attend daycare and preschool. Because of the numerous viral agents involved and the many serotypes of several viruses (especially RV), younger children having new colds each month during the winter season is not unusual. Adults and adolescents typically have 2-4 colds per year...
The optimal temperature for RV replication is 33-35C. ( 91F > 95F degrees peaking at 92F) RV does not efficiently replicate at body temperature. This may explain why RV replicates well in the nasal passages and upper tracheobronchial tree but less well in the lower respiratory tract. The incubation period is approximately 2-3 days..."
The optimal temperature for RV replication is 33-35C. ( 91F > 95F" The cause of these symptoms is the immune response. Cells under attack by rhinoviruses release chemical signals called cytokines to attract immune cells and warn neighbouring cells that they are infected. These cytokines attract immune cells and stimulate a cytokine cascade, which further amplifies the immune response. More chemical messages are sent that result in the dilation of blood vessels in the area surrounding infection. They also increase blood vessel leakiness, glandular secretion, and stimulate nerve fibers. The end result is symptoms of the common cold: sore throat, runny nose, watering eyes, sneezing, coughing, congestion and headache.

So advice is during the night in bed is to keep ones head, throat, and upper chest, warm so nasal passages are too warm for viruses to easily multiply and make a colonizing beach head where our immune systems cannot remove them faster than they multiply.
